WinSCP C# Library - Cannot open file “\\.\nul”. Access denied

Hello all !
I have a Raspberry Pi with SFTP enabled for one user which is "wifi". When I connect using Filezilla client, it works great. But when I use the WinSCP Library (the latest), it failed with

{WinSCP.SessionRemoteException: Cannot open file "\\.\nul". Accès refusé
   at WinSCP.SessionLogReader.Read(LogReadFlags flags)
   at WinSCP.ElementLogReader.Read(LogReadFlags flags)
   at WinSCP.SessionElementLogReader.Read(LogReadFlags flags)
   at WinSCP.CustomLogReader.TryWaitForNonEmptyElement(String localName, LogReadFlags flags)
   at WinSCP.CustomLogReader.WaitForNonEmptyElement(String localName, LogReadFlags flags)
   at WinSCP.Session.WaitForGroup()
   at WinSCP.Session.Open(SessionOptions sessionOptions)
   at DumboNetwork.Controllers.SFTP..ctor(String args)}
Here is the code used

sessionOptions = new SessionOptions
            {
                Protocol = Protocol.Sftp,
                HostName = args,
                UserName = "wifi",
                Password = "password",
                SshHostKeyFingerprint = "ssh-rsa 2048 6c:53:02:91:9f:08:3d:a1:d3:45:e5:67:8a:88:f8:14",
                GiveUpSecurityAndAcceptAnySshHostKey = true,
                PortNumber = 22,
            };
            client = new Session();
            client.SessionLogPath = ApplicationData.Current.LocalFolder.Path + "\\" + "debug.log";
            client.DisableVersionCheck = true;

            int attempts = 0;
            do
            {
                try
                {
                    client.Open(sessionOptions);
                }
                catch (Exception e)
                {
                    attempts++;
                    Debug.WriteLine(e);
                }
            } while (attempts < _connectionRetryAttempts && !client.Opened);
Can you help me ? Thanks !
